Extending the range of Electrical Performance Testing services offered, our firm routinely conducts comprehensive Over-the-Air (OTA) Testing for network device certification.
We engage leading CITA-Certified facilities to conduct mobile network operator certifications from 450 MHz to 10 GHz. We offer TRP testing for NR, LTE, UMTS, along with protocol specific technologies such as Carrier Aggregation.
Each HBR OTA report provides a comprehensive breakdown of 2D and 3D radiation models at each carrier under passive and active tests, along with tabulated data of conducted power and sensitivities at individual channels or pre-specified frequencies.
An explanation of key terms is provided below for your reference.
Total Radiated Power (TRP)
TRP defines how much power is being radiated from the device and is measured in dBm. The higher this number, the better the device is able to transmit. This figure is most impacted by antenna design and placement and its testing is often necessary to improve overall device performance.
Total Isotropic Sensitivity (TIS)
TIS defines how low a signal the device can receive and demodulate, and is also measured in dBm. The lower this number the better the device can operate in weak signal environments. This figure is most impacted by internal device noise and its testing is often used to improve the device design.
Radiated Spurious Emissions (RSE)
These are radio waves output by the device which are above the power limit set by regulatory authorities to avoid interference. When a test confirms a radiated spurious emission over the limit either the device or the antenna must be modified to get it below the limit and hence pass certification. Otherwise the device cannot be sold in that country. Typically this is the most challenging test for a device to pass.
